Acoustic Insulation for Marine & Offshore

Sound absorption in Marine Shipbuilding

Acoustic insulation standards on board, especially in passenger ships, are continuously rising. With ISOVER ULTIMATE products whose acoustic insulation properties are improved by up to 50%, it is easy to make that decisive leap forward and provide state-of-the art acoustic solutions.
With ISOVER ULTIMATE you can achieve identical sound absorption properties at only around half the weight of traditional stone wool - saving you time and weight. And your passengers and crew? With ISOVER ULTIMATE they get improved acoustic comfort due to its high-level sound absorption properties and very good sound reduction.
